⚠️ WHY IS COMPLETE WATER PUMP RENOVATION CRITICAL?

A functioning water pump is crucial to the survival of your Mercury 4-stroke! Worn components can lead to:

• ❌ Engine overheating

• ❌ Broken gaskets and seals
• ❌ Total breakdown (can cost SEK 40,000-100,000!)
• ❌ Stretched out on the lake

🔥 With this complete kit you can renovate the ENTIRE water pump – including the housing!

💡 EXPERT ADVICE FOR MERCURY 4-STROKE OWNERS:

• 📅 Replace every 3-5 years – or every 300 operating hours for 4-strokes
• 🔍 Inspect the cooling water body – weak jet = warning!
• 🏠 Renovate the ENTIRE pump – replace housing, impeller and gaskets at the same time
• 🧰 Use lubricant – when assembling the impeller
• ⚙️ Check all O-rings – replace ALL seals
• 🌊 Saltwater farm? – inspect more often (every season)
• 🔑 Impeller Key – make sure the key is seated correctly
• 📝 Document – ​​write down dates and operating hours
